I'm a bit weary about using a memory allocator from a research paper. There are alternatives that are actively developed and regularly used in production systems, like OpenBSD malloc and Copperhead malloc. They also do not come with the risk of the authors not maintaining the source as they move on to another research project. Personally, I would very strongly recommend the Copperhead malloc, as it's an improvement over even the OpenBSD malloc in quite a few ways, and has some very interesting hardening techniques planned for the future.
